In this paper, using the notion of the tight integral closure, we will give a criterion for F-rationality of Rees algebras of ᒊ-primary ideals in a Ž . Cohen᎐Macaulay local ring. As its application, we prove the following results: 1 In dimension two, if A is F-rational and I is integrally closed, th
